Add ID to USB drive into MS Excel

[sswcharlie]

Hi

Have a USB RFID reader which uses a keyboard wedge. Works as it should.
However I would like to use two or more of these readers, all using the keyboard wedge, and have the ID of the USB reader (prefix or suffix) used each time added to the read number for the tag.

So need some software between the reader and the keyboard that adds the USB ID.

Any ideas how to do this.
